Because we are a company that promotes from within, some people interpret that as a promise. Some co-workers of mine have felt they were overlooked or have been "stuck" in a position. You need to be realistic about how long it can take to advance a career. This job/company is fast paced, so change happens quickly sometimes (especially during busier holiday season) but that doesn't mean you don't have the work and earn the extra opportunities. I think TP could sometimes be more straightforward about the opportunities that are open. I think we set everyone up to think they WILL succeed quickly, and when they don't, they blame us (when its really they're performance/attitude etc).
Pay is not necessarily the highest compared to other call centers. But the range of experiences I've had, that I can now put on a resume. and the fact I love my job, make it worthwhile for me.
